These platforms support the use of the external SD card slot or external compact flash (cf2:\) to boot the system. Use the storage media supplied with the purchase of a valid satellite mode license. After you insert the storage media in the external storage media slot, ensure that the satellite is connected to the host before you power on the system.
Table: Uplink ports used for 7210 SAS platforms and variants in satellite mode lists the uplink ports used for 7210 SAS platforms and their variants. To boot up in satellite mode, the uplinks must be connected to the host ports, as described in Table: Uplink ports used for 7210 SAS platforms and variants in satellite mode.
The following notes apply to the host port information listed in Table: Uplink ports used for 7210 SAS platforms and variants in satellite mode:
In satellite mode, you cannot configure the BOF parameters uplinkA and uplinkB ports for use with auto-init. For successful boot up in satellite mode, only use ports specified in Table: Uplink ports used for 7210 SAS platforms and variants in satellite mode as uplinks to the 7750 SR host; use of other uplink ports is not supported. See Configuration notes for 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, 7210 SAS-Sx 10/100GE, and 7210 SAS-Mxp for information about ports used for first-time boot up with the chassis-role set to factory-default.
On the 7210 SAS-Sx 10/100GE operating in satellite mode, you can establish a connection to the host with one 100 GE or 10 GE uplink. However, Nokia recommends that you use more than one uplink based on capacity requirements and to provide redundancy.
On the 7210 SAS-Sx 10/100GE, by default, the DHCP requests are sent through ports 1/1/65 and 1/1/66, followed by 10GE ports 1/1/1 and 1/1/2. However, to use ports 1/1/1 and 1/1/2 as uplink ports in satellite mode, you must first appropriately configure the ports in the 7750 SR host machine.
See the 7210 SAS Software Release Notes 22.x.Rx, part number 3HE 18217 000x TQZZA, for information about the 7750 SR platforms and releases that support Ethernet satellites, and the version of 7210 SAS satellite mode software that is compatible with a specific version of SR OS software.
On the 7750 SR, the 7210 SAS-Sx 10/100GE 100GE uplink ports are referred to as u1, u2, u3, and u4:
On the 7210 SAS-Sx 10/100GE 64SFP+ 4QSFP28 variant, ports 1/1/c65 to 1/1/c68 map to front panel ports 1/1/c1 to 1/1/c4.

After the uplinks are connected and the node is powered up, the satellite node sends out DHCP packets. The host matches the MAC address in the DHCP packet against the host configuration to identify the satellite and provides the correct BOF to the satellite node for booting up. The BOF sets the host-type command to satellites and also provides the location of the TiMOS (SR OS) image and configuration file. The boot loader fetches the TiMOS image and configuration file and boots up in satellite mode.
When operating the 7210 SAS platform in satellite mode, Nokia recommends to use only the auto-init procedure to retrieve the BOF and other boot parameters from the host. Other procedures, such as the manual configuration of the BOF, are not allowed. See Auto-init mode for more information.
